Quantitative introns. to investigate the possible presence of introns in three newly discovered genes (x, y, and 2), youperform an experiment in which the restriction enzyme haelll is used to cleave either the dna of each gene or the cdnamade by copying its mrna with reverse transcriptase. the resulting dna fragments are separated by gel electrophoresis,and the presence of fragments in the gels is detected by hybridizing to a radioactive dna probe made by copying theintact gene with dna polymerase in the presence of radioactive substrates. the following results are obtained: . urce of dna number of fragments after source ) what can you conclude about the number of introns present in gene x? (b) what can you conclude about the number of introns present in gene y? (c) what can you conclude about the number of introns present in gene 2?
